CLUTCH.

SPECIFICATION formingpart of Letters Patent No. 258,968, dated June 6, 1882.

Application filed March 24, 1882.

To all lwhom it may concern:

Be it known that I, EDWARD WILKINSON,

a citizen of the United States,residing at Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Clutches, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The object of my invention is the production of a clutch that can be started without shock to the frame, which I accomplish by the devices and mechanism illustrated in the accompanying drawings, in which- Figure lis a front View of my newly-invented device, showing the parts open. Fig. 2 is a section of the same. Fig. 3 is an end view showing the teeth or lugs of the slidin g clutch,

and recesses or openings, hand-wheels', frame,

te.; and Fig. 4 is anl end view showing the friction-clutch.

ce represents a connected shaft, that connects with the drivin g-shaft'c. The connectedshaft a is provided with a key, a?, by which the drum d is secured to theT connected shaft a. The drivin g-shaft a' 'and connected shaft a are journaled in the ends of the frame b.

k 7a' are two collars, that are constructed in two separate parts, that are provided with lugs k2 and are bolted together by bolts k3. v Each of the separate parts of the collars 7c k is provided with pinsn n', that are formed thereon. The pins n n pass through holes that are provided for them in the shifting-arms jj', that are formed with openings in the center, that span the ends of the friction-cone g and clutch c. One of the ends of the shiftingarmsjj enters slots j2 jz, which are formed in the side of theframe b. The other ends of the same have forks formed on them, that lie in recesses formed for them in the sliding or screw nuts f2f3, that work on screws e andft, by the use of which screws the device is operated by means of the nuts f2 f3, the shifting-arms jj', and handwheels e andf. The screw e is a lincscrew, and is provided with a stem. On or over said stem works the screw f4, which is hollow. The screw e is journaled and supported in the frame b and bracketor stop b4, that is bolted to the side of theframe`b3, the bracket serving the double purpose of a support andstop for the screw e to prevent the screw from moving laterally. The stem of the screw e', over 1 clutch c.

(No model.)

- the frame b to accommodate the hand-wheel e,

by which the screw c is operated. The end of the hollowscrew f 4 passes through the frame b, also to accommodate the hand-wheel f, that is provided with handles f for operating the hollow screw f4 in opening and closing the On the driving-shaft a there is arranged a sleeve, h, that is keyed on the shaft. The sleeve is provided with a feather, o', on and over the sleeve h, and feather o works a sliding friction-cone, g, the periphery and face of which has arranged in it round perforations p, that are filled with plugs of any suitable ma-V terials thought to be best to create friction. The friction-Coney has on the inner surface of its hub a Vchannel or groove to accommodate .the feather o', over which the friction-cone slides, the feather o servingto keep the friction-cone g fast for rotatingr` purposes. The drum d, on its inner surface, is of conic form, and corresponds with the form of the cone g on the friction side of the drum d. The clutch side of the drnmd is provided with openings' m in the disk, corresponding in size and form wit-l1 the teeth or lugs m of the clutch c. On the connected shaft a there is a loose collar, t', that serves to cover the key i', that keys the drum d to the shaft a.

My device operates as follows: When the A simple and easy method of turning the hand-A wheel e the friction-cone gis carriedlin the drum d, causing the frictionplugs to impinge against the inner conic surface ofthe drum d, rotating the same by the friction thus created by the impingement of the surfaces. By turning the hand-wheelf to the left the screw-nut f3 is caused to travel on the hollow screw f4, carrying with it the fork end of the shiftingarm j, the forks of which lie in the recesses formed in the screw-nutfs, and by reason of the plus n, that pass through the arm i, move the clutch cin the direction ofthe drum d, bringing the clutch c and drum d into engage- IOO ment, all of the rotating parts havin g been set in motion by the friction-cone g in the manner before stated. rlhe teeth or lugs m pass through the openings m in the drum d. The 5 lugs m,that are formed as shown on their ends, present their foremost and longest parts,whicl1 enter openings m', formed in the flange of the friction-wheel g, and find their bearings in the same, creating thereby positive or forced motion, without shock or jar to the frame. To disengage the engaging parts the turning of the Wheels ef is reversed. l In the hub of the friction-Wheel g there is formed a groove, q, Fig. 2, the object of 4Which is to hold the escaping oil near for lubricating the ends of the shafts until the same, by centrifugal force, shall pass out through the oilliole t,tormed in the flange of the Wheel g. By this means the escaping oil is prevented from lreaching the friction-cone g, which would, should the oil reach the same, prevent friction. When the parts are in engagement the collar t enters the groove q, and thereby prevents the oil from escaping except through the z 5 oil-hole t', as before stated.

Having described my newly-invented friction-clutch and its mode of operation, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination of the drum d, frictionwheel g, collar k', sleeve h, feather o, pins n', perforations P, shifting-arm j', screw-nut f2, screw e', hand-wheel e, stop b4, slot jz, frame -b, frame b3, frame b, and shaft a', substantially ED WARD WILKINSON.
